FIELD: engines and pumps.
SUBSTANCE: invention relates to a pump for pumping high-density powder. Pump comprises four pump chambers and operates in four-stroke mode. In fact, four pump chambers form a system consisting of two pairs of chambers arranged in series. This enables separation of total flow rate per minute into four reservoirs. Each of four tanks has reduced capacity, providing advantage of compactness of pump and shorter loading/unloading of one tank.
EFFECT: using laws of hydrodynamics on interconnected vessels and by means of constant underpressure, system consisting of pairs of chambers arranged in series, increases total volume for storage of powder.
